LOOK FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Application filed January 9, 1911. Serial No. 601,584.

is a specification, reference being had therein to the accompanying drawing This invention relates to improvements in looks for automobiles and other motor vehicles and its object is to adaptthe ordinary Yale type of lock to the purpose by connecting to the rotatable barrel of such a lock, means for transmitting motion from said barrel to the part to be operated and providing thebarrel with means for'yieldingly holding the same from turning to hold the part actuated therebyin the position to which it is turned when the barrel is act-uated by its key.

To this end the invention consists in the matters hereinafter more fully .set forth, reference being had to the accompanying drawing in which,

Figure 1 is a side. elevation of a device embodying the invention, showingthe same in operative position; Fig. 2' is a perspective view of the lock detached from its cas- 30 ing; and Fig. 3 shows a modified application of the invention. For convenience of illustration, the lock is shown as applied to the controlling of the fuel supply to the motor of the vehicle, a suitable valve 1 being provided in the gasolene supply pipe 2 which valve is operated by means of a flexible shaft 3 attached to the stem of the .valve and extending upward within a-suitable shield or casing 4 secured to the forward side of the dash board 5 or other part of the automobile body adapted to serve as a convenient support therefor.

The upper end of the flexible shaft 3 is jointedly connected to the inner end of the rotatable bolt-6 of an ordinary lock 7 of the Yale type, by a ferrule 8 secured upon the end of the shaft and formed with a transverse eye to receive a pivot pin 9 passing through holes in ears 10 projecting from the end face of a squared end or head 11 on the inner end of the bolt 6. The lock is inclosed within a suitable casing 12 provided with a flange for securing it to the rear side of the dash in .an inclined position, the end flange 13 on the barrel 14 of the lock fitting within the end of the said casing in the usual manner. At its inner end, the barrel 14 is formed with a projecting lug 15 forming. a stop to be engaged by a lug 16 on the end I f the bolt 6 and limit the turning of said bolt by its key 17. The barrel is also cast with a ledge 18 at each side forming a place of attachment for a U-shaped spring 19 whichis secured thereto by screws with the connecting end portion of the spring lying flat upon one side of the square head 11 of the bolt. When the lock is in place within the casing 12, said casing incloses and protects the sprlng as well as all of the other parts. The stop 15 limits the turning of the flexible shaft so that it may not be turned farther than necessary to open or close the valve and the spring 19 yieldingly engaging the squared head, holds the bolt turned with the valve in either open or closed position so that it will not be turned by the jar-and vibration of the vehicle. By this construction a very neat and compact locking device is secured which may be connected by means of the flexible shaft with of the automobile mechanism controlling its use, and the lock located'in any convenient place. In Fig.3, the flexible shaft is shown as supported and guided by a pipe 20 through which it passes, a casing for the shaft.

What I claim is 1. A device for the purpose described comprising a lock havin a stationary barrel and a rotatable bolt in ing an end extending beyond the barrel and formed with a plurality of faces, a spring secured to the barrel in engagement with one of said faces to yieldingly hold the bolt from turning, a tubular casi-n inclosing the 9 barrel and spring, and a she. pivotally attached to the extended end of the bolt at one end. 7

2. A device for the purpose described comprising a lock having a stationary bar- 100 rel and a rotatable bolt formed with a' squared end projecting beyond the barrel, said bolt and barrel being also formed with projections forming stops to limit the turning of said bolt, a U-shaped spring secured 105 at its ends to the barrel with its connecting middle portion engaging the squared end of the bolt, a tubular casing inclosing the barrel and spring, and a shaft attached to said end. of said bolt;
